Tube Preamps Should Have This Feature

So it's late or you just want some casual listening for a short time. "Should I fire up my tube pre for 30 minutes?". My answer is "No". Why not let me flip a switch (or push in the volume control) to put my pre into "bypass" mode? Bypass would, effectively, convert your pre into a passive device, keeping the tubes dark.

This sounds useful to me.

Two issues come into play: 1. My preamp uses four 6H30 tubes (and two tubes which I assume are rectifiers). It’s very hard to acquire GOOD 6h30 tubes these days so, until Western Electric can clone 6H30-DR (Russian mil-spec and the best I’ve heard), I’ve got to conserve. 2. I worry about the thermal effects doing damage over time. I’m also retired and trying to live off only SS. I’m also Scottish who are known to be somewhat "thrifty" so that comes into play. It would just be nice to have the option to NOT burn tubes if I’m going to bed in 20 minutes but want to hear some tunes.

I've heard "Life is what you make it" but I never got the instruction manual.
